The portable analyzer shall be operated in accordance with the Environmental Protection Agency’s, Office of Air Quality Planning & Standards, Emission Measurement Center Conditional Test Method - Determination of Oxygen, Carbon Monoxide and Oxides of Nitrogen from Stationary Sources for Periodic Monitoring (Portable Electrochemical Analyzer Procedure) [CTM-034] (September 8, 1999). NOx emissions shall be corrected/calculated in units of the underlying applicable emission limitation (grams per horsepower hour, pounds per MMBtu, pounds per hour).

Quarterly n/a* PMG-LF-N-044


Fuel Consumption. Measure and record fuel consumption. Establish a maximum fuel consumption limit using the most appropriate of the following: the most recent performance test data, manufacturer’s recommendations, engineering calculations, and/or historical data. The monitoring instrumentation shall be maintained, calibrated, and operated in accordance with the manufacturer’s specifications or other written procedures. Any monitoring data above the maximum limit shall be considered and reported as a deviation.











NOx Concentration. Measure and record the nitrogen oxides concentration of the exhaust gas on an annual calendar basis using the method specified in 30 TAC § 117.8000(b) - (d). The maximum NOx concentration (specified in units of the underlying applicable requirement) is the corresponding nitrogen oxide limit associated with the emission limitation in the underlying applicable requirement. The monitoring instrumentation shall be maintained, calibrated, and operated in accordance with the manufacturer’s specifications or other written procedures. Any monitoring data above the maximum limit shall be considered and reported as a deviation.

Annually n/a* PMG-LF-N-047










NOx Concentration. Measure and record the nitrogen oxides concentration of the exhaust gas on a biennial calendar basis using the method specified in 30 TAC § 117.8000(b) - (d). The maximum NOx concentration (specified in units of the underlying applicable requirement) is the corresponding nitrogen oxide limit associated with the emission limitation in the underlying applicable requirement. The monitoring instrumentation shall be maintained, calibrated, and operated in accordance with the manufacturer’s specifications or other written procedures. Any monitoring data above the maximum limit shall be considered and reported as a deviation.

Once every two years n/a* PMG-LF-N-049






NOx Concentration, and:

Monitor and record the nitrogen oxide concentration in the exhaust stream each quarter that the emission unit is operational using a portable analyzer to monitor nitrogen oxide. The portable analyzer shall be operated in accordance with the Environmental Protection Agency’s, Office of Air Quality Planning & Standards, Emission Measurement Center Conditional Test Method - Determination of Oxygen, Carbon Monoxide and Oxides of Nitrogen from Stationary Sources for Periodic Monitoring (Portable Electrochemical Analyzer Procedure) [CTM-034] (September 8,1999). NOx emissions shall be corrected/calculated in units of the underlying applicable emission limitation (grams per horsepower hour, pounds per MMBtu, pounds per hour).

Quarterly n/a* PMG-LF-N-050


Fuel Consumption. Measure and record fuel consumption. Establish a maximum fuel consumption limit using the most appropriate of the following: the most recent performance test data, manufacturer’s recommendations, engineering calculations, and/or historical data. The monitoring instrumentation shall be maintained, calibrated, and operated in accordance with the manufacturer’s specifications or other written procedures. Any monitoring data above the maximum limit shall be considered and reported as a deviation.
